` To all whom it may concern? Be it known that I, JOHN C. TITUS, of Marion, Marion county,Ohio, (post-oftice address Marion, Ohio,) haveinvented certain new andv A5 useful Improvements in a Combined Carbureter and Gasolene-Regulator, of which the following is a specification. Y

This invention, relating to combinedcarbureters and gasolene.- regulators especially applicable to gasolene-engines, will'be readily understood from the following description, taken in conneotion'withv theaccompanying drawings, in which- Figure 1 is a vertical central section'of my improved carbureter and gasoleneregulator; Fig. 2, a horizontal Section of the same, and Fig.`3 a plan of the same with the needlevalve structure removed.

In the drawings, l indicates the body ofthe carbureter, illustrated as of hollow cylindrical form; 2, the outlet therefrom for the carbureted mixture, the same leading from vthe side of the body and being adapted for such con- ]nection as may be desired; 3, a cap-piece screwed firmly into the top of the body; 4, a large funnel-shaped air-opening vertically through the cap 3, the cap being provided with a downward extension, causing the lower extremity of this opening to be disposed well down within the body 1-at a pointabout level with the center of outlet 2 3 5, a top plate in the cap Sand forming a cover for the opening 4, this plate being pierced with registeropenings; 6, a registerivalve disposed concentrically upon the'top plate 5 and adapted for angular adjustment thereon, so as to regulate the amount of` air Vpassing from the atmosphere through the air-openingft; 7, the body of the gasolene-valve, the same being seadapted to be piped to any suitablesonrce of supply; 9, the needle-Valve for the control `off-the flow of gasolene; 10, an overflow-nose lSecured centrally in the floor of the body of the carburetor axially in line with opening 4;`

curedaxially in top plate 5; 8, the gasolenev inlet to the gasolene-valve, the same being -centric therewith ;v 13, an outlet-pipe screwed upwardly in the axis of nose 10, its upper end projectingan adjusted dist-ance into the cavity 12; 14, a stufing-box on the lower'end of Vnose l0 to pack around pipe 13 and permit of its being screwed up and down in the nose; 15, thelower end ofpipe 13, adapted for connection to a suitable pipe to carry away surplus'gasolene toa proper point ot' reception; 16, a rimextendingupwardly from the head of nose 10, concentrically around the base ot'- air-opening 4, the rear portion ofthis rim or that portion farthest' from outlet 2 being m uch `lower than that portion which is contiguous tothe outlet, and 17 the discharge-nozzle 'of` f the gasolene-valve, the same extending downwardly'through air-opening 4'and into cavityy 12its lower extremities being disposed to one 'Aside of the vertical plane of pipe 13. u

Ignore pipe 13 for theV present and assume that conical cavity 12 is closed at its bottom by any means. valve be opened and a quantity of" gasolene In suchucase it the gas'olene# f,

be allowed to'enter the cavity l2 and then a l draft'of air be drawn through the air-opening? 4 and the outlet- 2 the air 'entering the vcar- 1 bureter will impinge downwardly upomthe,l 8o.

gasolene in cavity 12 and will evaporateit and commingle with it, the mixture passing `over rim 16 and out at outlet 2.v If the-rim .y

16 were of uniform height around the baseof V air-opening 4,'the flow of air would be favored "j by outlet 2 andthe attack `of'air uponthe gasolene would besoinewhat one-sided in the cavity, thus interfering with the perfection of the carbureting.V By giving the-'frontof rim 16 a `superior elevation the favoring influence of the outlet on"th'e` air-current is neutralized and there is a fairlyconcentric attack of the air uponthe gasolene and ax fairly concentric flow ofuniformly-carbureted air from cup 16 into the body of rthe curbureter. Y .l f

It is foundinpractice` that in using this carbureter in connection with gasolene-engines it' the'air-infiow to air-opening 4 is unrestricted at the time Aof starting the engine some diiculty arises,'.which difficulty is removedby temporarily throttling the air-inflow.

ter-valve 6 when starting the en gine, the valve being later fully opened. y

lIco

This is done by partially 'closing regis- As thus far considered the bottom of gaso- Alene-cavity 12 has been assumed as stopped up, so that the cavity formed a mere cup to hold the charge of gasolene. This would require very accurate and delicate adjustment of the gasolene-valve in order that the amount of gasolene delivered in the cup should be just right for each charge; but by the use of overflow-pipe 13 the charge of gasolene in cavity 12 is received around the upwardly-projecting end of pipe 13, the surplus overflowing through the pipe. By adjusting pipe 13 vertically the retained charge may be adj usted to a nicety, quite regardless of any delicate adjustment of the gasolene-valve. The sidewise deflection of the gasolene-nozzle 17 prevents the llow of gasolene directly downward into overflow-pipe 13.

I claim as my invention- 1. The combination, substantially as set forth, of a hollow carburet-er-body having a horizontal outlet, a gasolene-cup disposed in the base of said body and having its rim disposed inwardly away from the wall of the body and having a rim portion at and as high as said outlet, a top to said body having a portion projecting down thereinto and concentrically Within said gasolene-cup and having a funnel-shaped air-opening vertically through it, a gasolene-nozzle arranged to deliver into said gasolene-cup, and a valve to control the flow through said nozzle.
